Frustratingly enough, the jury is still out on this one. But in reading this article it does sound more promising than not. St. John's Wort, otherwise known as Hypericum Perforatum, has been used for more than 2400 years -- maybe even by Hippocrates himself. And in the majority of studies performed in both past and recent years there has been at least some relationship shown between taking the herb and experiencing a decrease in signs and symptoms of depression. There have been contradicting studies also, but they seem limited to how St. John's Wort affects people with minor symptoms compared to more serious ones.

Although it is generally mild and safe as far as herbal supplements go, don't take it too lightly. St. John's Wort can have some significant side-effects like dizziness, photosenstivity, and even decreased fertility. And never, ever, take St. John's Wort if you're already taking other meds for depression.

Bottom line? St. John's Wort may be right for you, but be sure to check with your doctor first.
